But Sony’s being a little more cautious with their similar Wii-killing device, the PlayStation Move. According to Sony Senior VP Ray Maguire, they expect sales to start slow, with momentum building over time.

“Exactly as with EyeToy in the PS2 days, it’s a product that needs to be sampled. You need to get your hands on it. You need to understand it. You need to try it,” said Maguire in an interview with Eurogamer.

“Am I expecting a massive day one? Not particularly. We didn’t with EyeToy, either. It went on to be massively successful. As people saw the value when they tried it they told their friends. Their friends bought it. They told their friends. Word of mouth grew the marketplace. That’s what I expect from Move as well.”

Sony’s Move is a simpler approach to motion control than the Kinect… but it works, and works well. Could Sony’s modest technology and long tail gameplan succeed where the Kinect’s bolder approach completely crashes and burns?
